I've been in posession of this propeller for many years. I'm finally getting around to trying to identifying it. Any help would be greatly appreciated.

Lengh-100 inches
Hub diameter 8 inches
8 Bolts in the hub

Writing on hub: TCHECOSLOVAQUIE PRAHA WALTER CSR

PRAGUE WALTER

Other marking: D-950 (stamped into blade)

Hi,

Markings on the metallic hub seems from Walter (a Czeh engines manufacturer, see this page: http://en.wikipedia.org/wiki/Walter_Aircraft_Engines) but the prop itself could be american: I think I see "... propellers" on the top of the decal and "USA" on the bottom.

Regards,
PM

Hello,

Thanks, yes I did determine the hub had Czech markings on it, but was wondering how and why a Czech hub would end up on a US made propeller.

Looking at the history of Walter engines in the link Pierre Michel posted above, I notice a variety of engines that were produced under license. It wouldn't surprise me that hubs and propellers may also have been produced under license, and your prop may have a U.S. counterpart of some kind.

Dave,

Thanks, I did look at the website and this could be a possibility. I'd like to know if anyone can recognize the label on the blade. I've not come across anything yet that looks similar.

Happy New Year for all propeller snoopers... and for others also!

Happy New Year, PM and others!

That does look like a Stone decal and the prop itself is consistent with a Stone design, from the Stone props I've seen. (Picture here.)

Any thoughts on what type of airplane this might have been attached to, given the manufacturer and the hub? Also, any thoughts on what the propeller might be worth?

Thanks,

KTE
